patch reverted
i had checked the spec before appying it but ive missed or
misinterpreted it and thought the dts=pts rule only applied to

For reference:
A PTS may only be present in a Rec. ITU-T H.222.0 | ISO/IEC 13818-1 video or audio elementary stream PES packet
header if the first byte of a picture start code or the first byte of an audio access unit is contained in the PES packet.
A decoding_timestamp (DTS) shall appear in a PES packet header if and only if the following two conditions are met:
              a PTS is present in the PES packet header;
              the decoding time differs from the presentation time.

Can you check if reverting this has any ill side effects ?
ive tried a few files and didnt notice a problem but iam not sure
which file the original patch was intended to fix.
Can you check ?

Thanks & sorry for the mess
